- Be it known that I, HENRY 'I. WrLLrs, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a certain new anduseful Improvement in Vapor-Generators for Bathing Apparatus, of whichthe following is a description sufliciently full, clear, and exact toenable any person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming apart of this specification, in whichFigure l is a vertical longitudinal section of thevapor-generatorforming a part of the apparatus. Fig. 2 is a perspectiveview of the perforated holder for containing the medicating ingredientsused in the generator.

Like letters and figures of reference indicate corresponding parts inthe diiferent figures of the drawings.

In Fig. 1 of the drawings, A represents the body or casing, 13 the domeor cap, and G the funnel 0r eduction-pipc. Arranged vertically, andproperly supportedwithin the body, there is a hollow sheet-metalcylinder, D, divided into three compartments or chambers, E, F, and G,and provided with the dome or cap H and funnel I. A coiled pipe orhelix, J, also properly supported in the body A, surrounds the cylinder,the lower end of the pipe being provided with a plug or cap, K, and theupper end turned downwardly, as seen at L, forming a coil, M, above theplatform N, and entering the cylinder D through its bottom at m A seriesof gas-burners, O, on which. the coil M rests, are disposed beneath thecoil J and cyliuder D, the burners opening upwardly through the platformN, and being supplied from any convenient source through the pipes P;but in place of the gas-burners either spirit or hydrocarbon burners maybe used, if desired. The body A is supported upon theverticallyadjustable legs Q, and provided with an auxiliary casing 01'petticoat, R. This casing has its bottom perforated, as shown at d, toadmit the air which passes out of the same and into the coil-chamber Sthrough the holes a a. The dome B is also provided with a similarcasing, T, which receives air through the perforated 50 bottom 2, anddischarges it into the funnel G, the dome and casing being properlyconnected at their bases. The bottom U of the compart- 'ment F isperforated and permanently fixed the perforated holder 45 for the herbs,drugs,

or chemicals used in medicating the vapors oi: the bath. the holderbeing also removable.

In the use of my improvement the domes B andH are removed and the tube Jpartly filled with water through the inlet 20, which is then tightlyclosed. The holder 45 is then filled with whatever substances are to beused in medicating the vapor and inserted in com-. partment F, as seenin Fig. 1, the pipe or funnel 0 being connected with the bath by anysuitable means. The burners O are next lighted. heating the water in thepipe J and converting it into stean1,which passes into the compartmentG, and thence through the bottom U into the compartment F, Where itbecomes medicated and passes into the compartment E, and from thencethrough the tube I into the tube 0, where it niixeswitli the hot air fro11 the chamber S and is carried to the bath. The pipe I is provided witha ball or floating valve, 22, by which the steam or vapor is held backor retarded in its progress through the cylinder D, thereby becomingsuperheated in the chamber or compartment G to such a degree as to actmore effectually on the contents of the compartment F, and also fullyutilize the heat of the burners 0.

The object of the auxiliary casing R is to utilize or save the radiatedheat of the body A, the air on the exterior of the body being heatedthereby and passed through the fines or openings to a into the chamberS, and thence into the pipe 0 through the openings 25 in the top of thedome B, around the pipe I, the radiated heat of said dome being alsoutilized in heating the air within the casing T, which passes directlyinto said pipe. The amount of hot air permitted to pass through the tubeC may be, readily governed by registers ordampers at the openings 25 andin the bottoms N d X. The steam or vapormay also be entirely shut offfrom the bathing couch or closet, or regulated as required by ordinaryvalves or dampers, or by a pi pe connected with a d I eeaece the pipe I,which may be properly arranged for that purpose; or the coil andcylinder may be removed i'romthe body A. When necessary, I connect atube with the chamber or compartment G and conduct the superheated steamto the burners O, delivering it in the center of the flame in such amanner as to increase its intensity and cause the lamps to burn in amuch better way; but this is not required when gas is used.

Having thus explained my invention, what I claim is- 1. The improvedsteamgenerator described,

the same consisting of the body A, dome B,

casings T and R, pipes J and C, burners 0,

cylinder D, and funnel I, constructed, com-' bined, and arranged tooperate substantially as set forth.

2. In a steam-generator substantially as described, the casings T and11-, in combination with the body A, dome B, and pipe 0, substantiallyas and for the purpose set forth.

3. In a steam-generator substantially such as described, the cylinder D,surrounded by the coil J and provided with chambersE, F,

and G, dome or cover II, and funnel I, substantially as and for thepurpose set forth.

4. In a bathing apparatus, the combination of a steamgenerator, ainedicating steam ch amber, and a superheating steam-chamber be, tweenthe steam-generator and medicatingchamber, substantially as described.

5. The combination of a vapor-chamber, a coil supplying the water to bevaporized, an inclosing-casing, burners for heatingthe water, anainconducting pipe leading from the top of said casing, and avapor-eduction pipe leading from said chamber and extending into anddischarging within said air-pipe, substan tially as described.

6. The combination of a vapor-chamber divided into compartments by meansof perforated diaphragms, a removable perforated receptacle for themedicating ingredients, adapted to fit within one of said compartments,

a coil for supplying water to be heated and vaporized, a casinginelosing said chamber and coil, means for heating, and suitable air andvapor conducting pipes leading from said chamber and easing,substantially as set forth.

7. A vapor-chamber divided into compartments by means of perforateddiaphragms, and

provided with a removable perforated recep tacle for medicatingingredients, substantially as described.

8. The combination of a vapor-chambena water-coil surrounding the sameand connected therewith, means for heating, a casing inclosing saidchamber and coil, provided with an exterior air-conducting skirt, andwith apertures near the top of said-skirt for admitting the air,substantially as set forth.

9. The combination of a vapor-chamber, a water-coil surrounding the saidchamber and connected thereto, means for heating, a casing inclosingsaid chamber and coil, provided with a dome-shaped top and an exterior2tll-C()l1- ducting skirt surrounding the same, having an eductionrpipeconnected thereto, substantially as set 'forth.

10. The combination of a vapor-chamber, a water-coil surroundingthe'said chamber and connected thereto, means for heating, a casinginclosing said chamber and coil, provided with a dome-shaped top,separate air-conducting skirts surrounding said casing at the sides andtop, said casing being provided with air induction and eductionopenings, substantially as set forth.

11. A vapor-chamber divided into compartments by perforated diaphragms,one of said compartments being adapted to receive medicatingingredients, andprovided at its top with.

a vapor-eduction pipe and an automatic valve, substantially as andforthe purpose set forth.
